Conservation of Energy
In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be create…

To determine

Why are aerodynamic drag coefficients of Formula One race cars typically much greater than for ordinary automobiles?

Expert Solution & Answer
Check Mark

Explanation of Solution

Aerodynamic drag coefficient is considered as dimensionless quantity which is used to compute resistance or drag of an object in an aerodynamic or fluid environment. It is related with a specific surface area.

Formula One race cars were mainly designed to attain high top speeds and the key objective was to reduce the air drag. Although at top speeds, car develops a lift force that affects the stability of car.

Thus aerodynamic drag coefficients helps in minimizing drag, wind noise, and eliminating unnecessary lift forces at top speeds. Air is considered as fluid in this environment.
